Description

Astronomers use telescopes with photometers to measure the brightness of stars. However, all photometers are different so astronomers have designated certain stars as standards and assigned them a standard brightness, called magnitude. Astronomers observe these standard stars and adjust their data to give the standard magnitude. By observing standard stars in the star cluster M67 and comparing data collected with the CCD photometer at Andreas Observatory with the standard magnitude of these stars, we can reduce our data for all the stars we observe to the standard system. This research was partly supported by a Learning By Doing grant from MnSCU.
